In this HashiCorp Terraform configuration example article, I am using if condition to filter list of variable objects. Here in this configuration I am have multiple list of resource group, Their name and location are different in the variable objects as mentioned below. 

I want to deploy only resource group from WestUS location. Inside the loop, I am using if condition to filter the location. Which will only deploy resource group for given WestUS location.

# Configure the Microsoft Azure Provider
provider "azurerm" {
  features {}
}

variable "rginfo" {
    type = list(object({
        name = string
        location = string
    }))
    default = [
        {
            name = "west_rg"
            location = "WestUs"
        },
        {
            name = "east_rg"
            location = "EastUs"
        }
    ]
}

resource "azurerm_resource_group" "example_error" {
    for_each = {
        for rg in var.rginfo : rg.name => rg
        if rg.location == "WestUs" # && contains(keys(rg), "rg.location")
    }
  name     = each.value.name
  location = each.value.location
}

This is my plan, where it will only add one resource where location is WestUS.

terraform plan

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # azurerm_resource_group.example_error["west_rg"] will be created
  + resource "azurerm_resource_group" "example_error" {
      + id       = (known after apply)
      + location = "westus"
      + name     = "west_rg"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.

This is the screenshot of the terraform plan.
